HXNORMALIZE(1) HTML-XML-utils HXNORMALIZE(1) NAME hxnormalize - pretty-print an HTML file SYNOPSIS hxnormalize [ -x ] [ -X ] [ -e ] [ -d ] [ -s ] [ -L ] [ -i indent ] [ -l line-length ] [ -c commentmagic ] [ file-or-URL ] DESCRIPTION The hxnormalize command pretty-prints an HTML or XML file, and also tries to fix small HTML errors. The output is the same file, but with a maximum line length and with optional indentation to indicate the nesting level of each line. OPTIONS The following options are supported: -x Applies XML conventions: empty elements are written with a slash at the end (e.g., <IMG />) and, if the input is HTML, any `<' and `&' inside <style> and <script> elements are escaped as `<' and `&'. (The input is assumed to be HTML unless the -X op- tion is present.) Implies -e. -e Always inserts endtags, even if HTML does not require them (for example: </p> and </li>). -X Makes hxnormalize assume the input is well-formed XML. It does not try to infer omitted HTML tags, does not assume elements such as <img> and <br> are empty, and does not treat `<' and `&' in- side <style> and <script> as normal characters. -d Omit the DOCTYPE from the output. -i indent Set the number of spaces to indent each nesting level. Default is 2. Not all elements cause an indent. In general, elements that can occur in a block environment are started on a new line and cause an indent, but inline elements, such as EM and SPAN do not cause an indent. -l line-length Sets the maximum length of lines. hxnormalize will wrap lines so that all lines are as long as possible, but no longer than this length. Default is 72. Words that are longer than the line length will not be broken, and will extend past this length. A `word' is a sequence of characters delimited by white space.) The content of the STYLE, SCRIPT and PRE elements will not be line-wrapped. -s Omit <span> tags that don't have any attributes. -L Remove redundant `lang' and `xml:lang' attributes. (I.e., those whose value is the same as the language inherited from the parent element.) -c commentmagic Comments are normally placed right after the preceding text. That is usually correct for short comments, but some comments are meant to be on a separate line. commentmagic is a string and when that string occurs inside a comment, hxnormalize will output an empty line before that comment. E.g. -c "====" can be used to put all comments that contain `====' on a separate line, preceded by an empty line. By default, no comments are treated that way. OPERANDS The following operand is supported: file-or-URL The name or URL of an HTML file. If absent, standard input is read instead. EXIT STATUS The following exit values are returned: 0 Successful completion. > 0 An error occurred in the parsing of the HTML file. hxnormalize will try to correct the error and produce output anyway. ENVIRONMENT To use a proxy to retrieve remote files, set the environment variables http_proxy and ftp_proxy. E.g., http_proxy="http://localhost:8080/" BUGS The error recovery for incorrect HTML is primitive. hxnormalize will not omit an endtag if the white space after it could pos- sibly be significant. E.g., it will not remove the first </p> from `<div><p>text</p> <p>text</p></div>'. hxnormalize can currently only retrieve remote files over HTTP. It doesn't handle password-protected files, nor files whose content depends on HTTP `cookies.' When converting from XML to HTML (option -X without option -x), any pairs of <![CDATA[ and `]]>' are removed and character entities < > " ' and & are expanded (to `<', `>', `"', `'' and `&', respec- tively), but any other character entities are not expanded. To expand other character entities, pipe the input through hxunent(1) first. To limit lines to a given number of characters, hxnormalize breaks lines at spaces (or inside tags). Some writing systems do not use spaces between words and thus hxnormalize may not be able to break lines, except at al- ready existing line breaks. To make short lines longer, hxnormalize will combine lines and replace a line break by a space, except in writing systems that do not put spaces be- tween words, where the line break is replaced by nothing. hxnormalize cur- rently only does the latter for Japanese, Chinese, Korean, Khmer and Thai. (The text must be correctly marked up with `lang' or `xml:lang'.) SEE ALSO asc2xml(1), xml2asc(1), hxunent(1), UTF-8 (RFC 2279) 7.x 10 Jul 2011 HXNORMALIZE(1)
